<h2>Description</h2>
<p class="Body">Creates a new instance of <a href="../_Body.htm">TPolygon32</a> 
  object and changes its shape similar to dilation (or erosion when <b>Delta</b> 
  is negative) morphological filters.</p>
<p class="Body">The direction of grouth is determined by the order of the points 
  in the contour. Positive direction is to the left of each line (see image below).</p>
<p class="Body">Using <span class="EmptyRef">Grow</span> method with <b>Delta</b> 
  = 0 will simply create a new instance of the polygon with the same data as in 
  original polygon. </p>
<p class="Body">The <b>EdgeSharpness</b> parameter controls generation of new 
  vertices. Its value range is [0&#133;0.99].</p>
